A common theme is the influence of Bilbo on Frodo. Since Bilbo has had so many adventures, he passes on his wisdom and stories to baby Frodo.

It could be the magic in the old tales or the beauty of the natural surroundings in the Shire. This theme of discovery and wonder makes the fanfictions really engaging.
One common theme is mentorship. Bilbo often acts as a mentor to Frodo, passing on his knowledge and experiences. Another theme is friendship. Their bond as hobbits is explored in many fanfictions.
